Stuart Broad is urging England to be patient on day two after his first-day half-century wrestled the momentum away from India in the second Test.
India will resume on 24-1 after the Nottinghamshire all-rounder's 64 inspired an England comeback at Trent Bridge from 124-8 to 221 all out.
Broad said: "We're still bang in the Test. We want to make further inroads on day two but we can't chase wickets.
"The key is being patient. If you do that something can always happen."
He added: "In that final session you saw that we didn't go chasing wickets, which is often tempting when you've been bowled out for a low total. We didn't start banging in bouncers, outswingers, inswingers...
"Saturday morning will be a key session for us but we will stick to our gameplans in the knowledge that if we restrict them to two, two-and-a-half runs an over then wickets can fall in a bunch."
Having won the toss, India certainly made the most of the swing- and seam-friendly conditions on Friday afternoon.
Andrew Strauss and Kevin Pietersen had dug in well following the early loss of Alastair Cook and Jonathan Trott, but when they fell so did England's middle order, with the hosts sent reeling by a mixture of fine bowling and poor shot selection.
Broad combined with Graeme Swann, though, to restore England's hopes with a much-needed ninth wicket partnership - and when James Anderson removed Abhinav Mukund with the first ball of the Indian reply, England were right back in the Test.
"Swanny and I decided to try and get some momentum back and take it to them after tea and it came off," said Broad.
"In fact, by the end we were probably disappointed not to have got more wickets. Still we are right in the game and looking forward to a key day on Saturday."
Swann himself was sent for a scan on his left hand after being hit on the glove by a lifting delivery from Praveen Kumar, although it was later said the off-spinner had sustained no significant damage.
Broad added: "Swanny asked me to say that it would take a broken leg to keep him off the field and he is hard as nails.
"I don't think it will be a problem for him and we'll certainly see him bowling at some stage if the seamers can't make the breakthrough."
