yeah about that, how come 88 is only a 54% shot over two overcards like AK? doesn't AK only have 6 outs?

42/48 * 41/47 * 40/46 * 39/45 * 38/44 = .497

which is the likelihood that neither an ace nor a king will appear. There are, of course, flush and straight draws to consider (for both players) and the possibility that an 8 comes.
