Hmmm... Well, against a "lagtard" I don't like this sort of hand as a cold 4bing hand. Much rather pick like KQ or something if the guy is playing loads of hands and not folding very much, we want to be playing hands that dominate his range and hands like

, whilst very pretty, don't do this. Much rather go for this against a tighter player, if at all.
Just wanna make a little comment on bet sizing too. Pre, this is a very small raise. Generally OOP my sizing would tend to be a little bigger, and I certainly would be going for at least 3x, normally pot, with most of the hands that I'm going to be 3/4bing out of the SB. In this situation, we're giving the guy great odds to call and play a bloated pot heads up and in position, which is basically never a good thing. Yes our hand does flop well, but these sorts of hands do play much better in position because we can have much greater control over the pot and find it much easier to realise our equity (seems like a very popular saying nowadays). To do this out of position, we basically end up getting over 200bbs in with a straight draw, which again I would rather not do.
As for flop, I don't like our sizing. We're rarely going to get any sort of hand to fold here, and if we're trying to induce, I would way way way rather do this with a hand that has immediate showdown value rather than a hand that is a bluff. We must remember that our actual hand is 10 high. It is the nut 10 high, but still very definitely a bluff. As such, I would definitely go for a larger bet on the flop to put a little more pressure on his range and hopefully fold out a bunch of the hands that aren't paired. We put ourselves in a bit of a coffin on the turn if we get called. We have too much behind to shove, bet folding would be really bleurgh, and by check calling we have essentially limited ourselves to only winning the pot if our hand improves, which it certainly won't do enough/enough of the time to make it profitable.
I am definitely interested to hear your thoughts on your sizing through this hand, and your decisiont to cold 4, and I hope (although can't guaruntee it) that people will be constructive rather than dicky about it.
