$20+2 NHLE HU Tourney: 4th Street Logic

[bonsaltron]

VILLAIN is playing great heads-up poker. Sticking in check-raises, not too loosely nor tightly, mixing up betting lines and keeping me off balance but not crazily. Could very well be a 2+2'er.

HERO has been on the opposite side of the momentum swing. I've been playing normal aggressive HU but probably closer to the tight tank than loose land. Check-raising only once or twice the last 40 hands or so.

500 in the pot, 160 to call

Current stacks~
Villain: 1525
Hero: 955
Choices:

A) Shove. I am at LEAST calling here, which at least reduces my stack to 800ish, meanwhile 660 in the pot. A raise offers villain roughly 800:1450 odds, or 5:9, blocking any of the draws or counter-fitting (assuming he has a pair) and simultaneously killing implied odds on river obv.

B) Call. Look for a red brick on river and check/call. A king with a good kicker will no doubt bet with a river 10[img]/images/graemlins/heart.gif[/img] not to mention the busted-draw-bluff equity.

C) Fold. My check-raises have been minimal and thus demanding respect, plus folding now would leave me intact with a grand and blinds still newborn at 10-20.

Advice?

Any commentary on the best line would be greatly appreciated.
