small pkt pairs on B or in CO against SB 3-ball

[thepizzlefosho]

I've been mulling over a bit of strategy and was hoping to get some feedback to see if this line of thinking is solid. Suppose that you have a 2p2 TAG type player (28/20 pf guy) in the SB, and you open in late position with a small pkt pair (7s or lower) and they 3-ball you. The BB folds and it is back to you.

Lately I have found that capping preflop has made these hands significantly easier to play. The reason being a couple of things...

1) against this type of player his 3-betting range is wider from the SB than anywhere else on the table. Typically this player is trying to push out the BB and get HU with me when he has a hand that is worth defending against a steal. Thus it is much more likely that I am ahead against his range, and also have more postflop fold equity (ie he doesn't necessarily have AK and is going to showdown).

2) When I cap the post flop play when the flop comes Axx is relatively simple. If I just call and my opponent leads out on an A-high raggy flop I don't know whether this is a c-bet with KQ, he has another low pkt pair, or he's got the A. However when I cap and he checks to me on the flop (which he will almost always do) when I bet out I folding just about any non-A or pkt pair hand. If I get called obviously it becomes a case of reading the board to see whether he is playing WA/WB or if I'm up against a draw. However a c/r makes this a pretty easy fold for me, and my play becomes significantly more straightforward for the rest of the hand.

Thus I feel like this play has a lot of benefit based on the Fundamental Thereom of poker. If I cap here with a decent range of hands including all pkt pairs as well as my really big aces and big pairs, then it becomes much more difficult to read my hand postflop. Also this tends to force this kind of villain to play more honestly after the flop since I seem more SD bound, so I have a better understanding of their holding.

Is this sound theory, or am I just spewing pf when I do this with 22 and 33?

(obviously some people would say I should change tables instead of having a TAG with position on me, but lets save that argument for a different thread)
