Although the whole thing with the processing power being used to slow the cybermen down worked quite well for me, and it least felt reasonably plausable to me, it used all the processing power it had on this one problem which would realistcly not leave power to do anything else. At least he didn't just wave his magic wand and they all died, as seems to be the general solution these days. At least it wasn't the power of love, and they actually had to do things and carry out some sort of plan.
Excepting that they only needed the processing power to brute force 3 moves a head in chess, and they took it from the cybermen actually doing something. But yeah, better than power of love stuff, but that's faint praise.
But he wasn't actually brute forcing 3 moves in chess. That's just what the Doctor wanted him to think. It was all a bit of a ruse. He said the Time Lords invented chess, hinting that he knew something that the cyber planner didn't, and that he could win. In truth he couldn't, because he had no secret chess move, but he convinced the cyber planner that he did. So the cyber planner used all that processing power looking for something that didn't exist, like looking for a shadow in the dark. That's why it used so much processing power that it slowed the other cybermen down.
However, that doesn't overlook the fact that the cyber planner shouldn't have cared in the first place. Even if the Doctor won with some "hidden" move, he still would have just killed everyone. Also doesn't overlook the fact that the Doctor couldn't used one of the hand-zapper things to kill it while he still had the foil on his face.

Why did they say that technically the bomb would make the planet implode, when at the end of the episode it clearly makes it explode?
An implosion can actually set off a minor explosion. An implosion creates a void which matter quickly attempts to fill, given a large enough force, the matter could collapse to a density more than normal, which would then cause an explosion. Supernovas behave this way, the outward force of fusion runs out and the inward force of gravity causes the start to first implode. Then, due to the creation of a black hole and the reaction of lots of matter falling into it all at once, there is an explosion. I'm not quite sure how it fully works.
Personally I think the end result in the episode seemed like an implosion. An explosion would've scattered the pieces of planet far and wide, while an implosion would have crushed the planet, whose pieces would then float apart, leaving what we saw at the end.
EDIT: Went back and re-watched the ending. While the debris left behind looks like that from an implosion, the actual event itself does look like a regular explosion.
